DESCRIPTION
This module implements version 4.0 of the Wordnik API
(). It provides a simple
object-oriented interface with methods named after the REST ones
provided by Wordnik. You should therefore be able to follow their
documentation only and still work with this module.
At this point, this module builds request URIs and ship them out as GET
methods to LWP::UserAgent. Response headers are checked for error codes
(specifically, throw exception on headers anything other than 2/3xx).
Response data is not post-processed in any way, other than optionally
being parsed from "JSON" to "Perl" data structures. Data::Dumper should
be of help there.
INTERFACE
CLASS METHODS
new(%args)
my %args = (
server_uri => 'http://api.wordnik.com/v4',
api_key => 'your key',
version => '4',
format => 'json', # json | xml | perl
);
my $WN = WWW::Wordnik::API->new(%args);
SELECTOR METHODS
All selector methods can be assigned to, or retrieved from, as follows:
$WN->method($value) # assign
$WN->method # retrieve
server_uri()
server_uri($uri)
Default $uri:
api_key()
api_key($key)
Required $key: Your API key, which can be requested at
.
version()
version($version)
Default $version: *4*. This module supports API version 3 and 4
(default).
format()
format($format)
Default $format: *json*. Other accepted formats are *xml* and
*perl*.
cache()
cache($cache)
Default $cache: *10*. Number of requests to cache. Deletes the
oldest request if cache fills up.
debug()
debug($debug)
Default $debug: *0*. Don't sent GET requests to Wordnik. Return the
actual request as a string.
OBJECT METHODS
word($word, %args)
This returns the word you requested, assuming it is found in our
corpus. See .
$word is the word to look up. %args accepts:
Default "useSuggest": *false*. Return an array of suggestions, if
available.
Default "literal": *true*. Return non-literal matches.
If the suggester is enabled, you can tell it to return the best
match with "useSuggest=true" and "literal=false".
phrases($word, %args)
You can fetch interesting bi-gram phrases containing a word. The
"mi" and "wlmi" elements refer to "mutual information" and "weighted
mutual information" and will be explained in detail via future blog
post. See .
$word is the word to look up. %args accepts:
Default "count": *5*. Specify the number of results returned.
definitions($word, %args)
Definitions for words are available from Wordnik's keying of the
Century Dictionary and parse of the Webster GCIDE. The Dictionary
Model XSD is available in
in GitHub. See
.
$word is the word to look up. %args accepts:
Default "count": *5*. Specify the number of results returned.
Default "partOfSpeech": *empty*. Specify one or many part-of-speech
types for which to return definitions. Pass multiple types as an
array reference.
The available partOfSpeech values are:
[noun, verb, adjective, adverb, idiom, article, abbreviation, preposition, prefix, interjection, suffix]
examples($word)
You can retrieve 5 example sentences for a words in Wordnik's alpha
corpus. Each example contains the source document and a source URL,
if it exists. See .
$word is the word to look up.
related($word, %args)
You retrieve related words for a particular word. See
.
$word is the word to look up. %args accepts:
Default "type": *empty*. Return one or many relationship types. Pass
multiple types as an array reference.
The available type values are:
[synonym, antonym, form, hyponym, variant, verb-stem, verb-form, cross-reference, same-context]
frequency($word)
You can see how common particular words occur in Wordnik's alpha
corpus, ordered by year. See
.
$word is the word to look up.
punctuationFactor($word)
You can see how common particular words are used with punctuation.
See .
$word is the word to look up.
suggest($word, %args)
The autocomplete service gives you the opportunity to take a word
fragment (start of a word) and show what other words start with the
same letters. The results are based on corpus frequency, not static
word lists, so you have access to more dynamic words in the
language. See .
$word is the word to look up. %args accepts:
Default "count": *5*. Specify the number of results returned.
Default "startAt": *0*. You can also specify the starting index for
the results returned. This allows you to paginate through the
matching values.
wordoftheday
You can fetch Wordnik's word-of-the day which contains definitions
and example sentences. See
.
randomWord(%args)
You can fetch a random word from the Alpha Corpus. See
.
%args accepts:
Default "hasDictionaryDef": *true*. You can ask the API to return
only words where there is a definition available.
INSTALLATION
To install this module type the following:
perl Build.PL
Build
Build test
Build install
or
perl Makefile.PL
make
make test
make install
DIAGNOSTICS
"Can't access '$key' field in class $class"
Private or inexistent member variable.
"Invalid argument key or value: '$type'"
Inexistent query parameter, or wrong value passed to existing
parameter.
"Parameter 'partOfSpeech' requires a reference to an array"
partOfSpeech => [qw/.../].
"Parameter 'type' requires a reference to an array"
type => [qw/.../].
"The operation you requested requires JSON to be installed"
perl -MCPAN -e 'install JSON'.
"Unsupported api format: '$format'"
Supported formats are 'perl', 'json', 'xml'.
"Unsupported api version: '$version'"
The only API version supported by this module is 3.
CONFIGURATION AND ENVIRONMENT
WWW::Wordnik::API requires no configuration files or environment
variables.
DEPENDENCIES
This module requires the core modules "Test::More", "version" and
"Carp", and "LWP::UserAgent" from "CPAN". Additionally, it
recommends-requires "JSON" from "CPAN" for getting data in Perl data
structures.
INCOMPATIBILITIES
None reported.
BUGS AND LIMITATIONS
On versions 0.0.1 and 0.0.2, creation of a second object would clobber
the first object's instance variables, resulting in unexpected
behaviour. This is fixed in 0.0.3.
Response data is not post-processed in any way, other than optionally
being parsed from "JSON" to "Perl" data structures. Data::Dumper should
be of help there.
Please report any bugs or feature requests to
"bug-www-wordnik-api@rt.cpan.org", or through the web interface at
.
TODO
Post-processing
Add filtering methods on response data.
Implement WWW::Wordnik::API::Response class to handle the above
